10 Claims.

This invention relates to securing devices.

Particularly, the invention has reference to the assembly into a substantially rigid unit of a plurality of securing devices, all of .a particular shape, as hereinafter more 'clearly set forth.

These devices are arranged in contiguous relationship, and are disposed adjacent each other in such manner that an adhesive, applied to the devices, becomes positively effective to retain the devices fixedly relatively to each other, and to the series.

In order to dispose securing devices in the manner set forth, it has been found, for the purposes of this invention, that it is necessary to relate them to each other so that a substantial pocket is produced adjacent the side faces of the devices. This has been accomplished by wracking, or in the broad aspect of the invention, by disposing the devices so that the front facesof the bodies of the devices will be obllquely disposed relatively to any plane intersecting all of the devices at substantially thesame point in each of them, or to a plane passed through the extreme edge portions of such devices, or so that planes which are perpendicular to the contact surfaces or lines of adjacent articles will be disposed obliquely to lines or planes intersecting the side edges of the devices at substantially the same point or position in each of said devices.

In my co-pending application, Serial No. 436,682 filed March 18, 1930, which has matured into Letters Patent No. 1,811,060, granted June 23, 1931, this invention has been shown applied to staples, and more especially, to U-shaped staples. Herein it is intended to disclose and claim the invention generically as applied to many other forms of securing devices. Furthermore this invention is not intended to be limited in its scope merely to the disposition of the devices in wracked, or in the specific relation set forth in that co-pending application; it may also have relation to the arrangement of devices of this character whereby substantial pockets are formed or where they already exist they are increased in size at the faces or edges of the devices for the reception therein of adhesive, applied thereat. Due to the greater surfaces provided by these pockets, as against the surface of the edges themselves, a firmer association of the devices with each other will necessarily result.

The apparatus, herein set forth, is intended to cooperate with series of securing devices, ar-

ranged in the manner specified, so that, even though such devices may be disposed at angles considerably beyond the normal angle at which devices of this character are intended to enter the medium with which they are to be associated, still the apparatus will be operativeto dispose such securing devices in the preferred relation to such medium, without any marked interference with the apparatus or the medium operated upon.

Other objects of this invention will be apparent from the description and the drawings which form a part of this specification or will otherwise be indicated herein specifically. The invention, however, isnot intended to be restricted to the particular articles of manufacture, nor to construction and arrangement of parts of apparatus, nor to the particular applications of such apparatus, as herein shown and described, nor to the specific methods of op: eration, nor to the various steps or details thereof, as the same may be modified and applied in various relations, without departing from the spirit and scope of the invention, practical embodiments of which have been herein illustrated and described without attempting to show all the various forms and modifications in which the invention might be embodied.

Figs. 13, 14, 15,.16 and 17, respectively, depict several of the types of assembled units contemplated herein. Where I have referred to. mean plane of the bodyherein, I- wishto be understood as'referring to thefollowing planes, for

example:

In Fig. 13 to a plane and parallel to face C.

- In Fig. 14 to a plane passing throughD'and E and parallel to face F. I V In Fig. 15 to a plane passing throughG and and parallel to face J.

passing through A and B In Fig. 16 to a plane passing through-K, L and pointM.

h In Fig. 17 to a plane passing through'N and Q and parallel to face P. 0n the drawings, an attempt has been made :to

disclose the invention as applied to various types of securing devices. However, it is not intended that this disclosure be taken as all inclusive, as

I the invention may be applied to many classes of securing devices other than those herein shown or described.

For the purpose of settingforth clearly and concisely one embodimentwhereby the invention may be effected,the construction, shown in Figs.

1 and 2, is-taken as an example. In that-particular case, aplurality of individual glaziers points 10 have been assembled so that their broad faces 12' are in abutment substantially through out. The bodies of the points are not arranged symmetricallywitht'relation to any line perpendicular to faces 12 but are'arranged symmetri cally relatively to .an imaginary plane 14, which is determined by the side. edges'ofeach ofthe points, and which is' obliquely disposed relatively to faces 12, and of course similarly obliquely disposed to the mean plane ofthe points. In this manner, the edges 16 0f the points are brought into such relation that, on one side of each point,

- it overlaps an adjacent point'and is overlapped -by-a point on the opposite sides,- while at the other side of the point, the reverse status, of the 'overlapping points is found.

In'those cases 'where the edge faces 18 of "such points are planar, the, planes thereof being su'b-' stantially perpendicular to the planes of faces 12,

andeven in such cases where a substantial rounding of edge faces ls occursmarked pockets 29-are produced by the disposition and overlapping of the points in the manner set forth. Such pockets provide increased surface withwhich may cooperate an adhesive material 22, which rnay .be of .anyparticular or desired composition. When such adhesive material is applied along edge faces 18,- due to the increased surface with which .the 'adhesive22 may now cooperate, there is secured a firm and positive bonding of the points to I each other, until their separation is desired.

While in Figs. 1 and 2, points of diamond shape have been shown, it -is easily understood thatpoints of triangular" contour might alsobe ar-,

ranged in the manner described, in which. case, onlythree-edge faces'would be dealt within se-' curing thedesiredpockets- The result, however,

would be substantially identical, and, therefore,

. is not herein shown.

In Figs. 3 and 4, the invention has beensnovrn devices.

therethrough of pin 40.

' as applied'to securing devices such as brads, pins,

or similar elements, which are substantially of T-cross-section. In arranging devices of this character to effect the purposes of the invention,

it is desirable that some surface of each device be formed in such manner that it may be positioned in contact with a supplementary surface of an adjacent device, in order'that; the devices be held firmly in desired relationship. In any case, however, the side edges of the devices are intended to be formed in the manner above'set forth, that is, substantially planar, or rounded, consisting of a'plurality of faces-the planes of the edge faces, when the devices have planar edge faces, being disposed substantially perpenso that adjacent" units are contiguous throughout at their side faces; the edge faces 32, however, are notwithin the same plane, althougha pla'ne'may .be so related to said edgefaces so that at leastlines in each of the faces will be contained in such a common plane. Such plane, however, would be'Lobliquely disposed relatively to any plane whichwould .be perpendicular to In the apparatus shown in Figs. 5 to-12, a construction similar" to that illustrated and de-,

scribed in myv copending application is disclosed.

However, the construction herein is modified toprovide means for driving, or otherwise positioning, securing devices, of the-character herein set forth," substantially in the manner described for .the apparatus f in myco-pending application.-

While the apparatus herein .is described in relation ;to the driving of staples such as shown in my c'o-pendingapplicatiomit is, however, to be understood that, by changes within the scope-of the ordinary mechanic, such apparatus could be designed to-drive' glaziers points, or brads, or

other sec'uringdevices ofxthe kind dealtwith in this application, in substantially the same manner-aswould be involved in thedriving of staples. Apparatus '34 is seed to comprise a base 36,

which may be formed inanywell-known man- 'ner.

stamping, from {which have been punched, ears It is here shown. as made up from a'metal 38. The cars are turned upwardly .from the base at opposite -sides thereof *toreceive, through openings therein, a pin 40 uponwhich the '.body

42' of the, apparatus is pivotally mounted.

The body consists essentially of a' sheet metal .or like member, bent into channel cross-section- At the endof the body adjacent pin40, theside walls of the channel are punched out, and a pair of lugs 44, thus formed, are bent downwardly and are provided with openings for the reception herein shown, the body is bent inwardly, at the upper ends of the side walls, to provide a pair of inwardly turned, longitudinallyextending In the construction flanges 46, for purposes hereinafter appearing.

. Received Within-thebody 42 is a member 48,.

substantially similar in cross-section to body 42,

but of smaller dimensions, so that a distinct spac-' ing. of the flanges 50 of such member and flanges 46, and of the side walls of the member and of the body, results. The member is tackwelded, or in any other manner secured to the body to retain the same firmly anchored relatively to the body. The forward ends of both the body 42 and member 48 are cut off in a plane disposed to the longitudinal extent of the body and member at an angle substantially thesame as that of the disposition of the planes of assembled staples, or like elements, relative to 'a plane having a common relation to all of the' elements, as seen in Fig. 6.

The flanges 50 provide a runway along which a pusher 52 may slide. The pusher consists of a U-shaped member 54 which is retained between the walls of the body 42 and of the member 48, and the flanges 46 and 50. The forward end of the U-shaped member is intended to engage against staples or similar devices straddling the flanges 50, and is cut off at an angle substantially the same as that in the case of body 42 and member 48. cross-piece of member 54 is extended down into the groove of member 48 a finger 58. The portion of the finger 58 received within the groove is but slightly smaller than the groove to permit free movement of the finger longitudinally along the groove. By means of a pair of notches 60 in the finger, at the point that the latter passes through slot 56, the finger is retained assembled upon the pusher, and is permitted slight oscillation laterally.

The finger, after it passes above the member 54, is bent 'rearwardly and so that it is closely adjacent the top surface of member 54. At its rear end the finger is bent upwardly to provide a finger piece 62, the ,rear end of the finger being retained beneath the lip 64, struck from the metal of member 54 and extending forwardly therefrom. The finger is thus retained for limited oscillation while the finger piece is disposed for cooperation with the fingers of an operator. The body of the finger, immediately at the finger piece, is cut away to leave a portion of the finger piece forming a tooth 66 which is intended to cooperate with a tooth 68, formed by cutting away a portion of a flange 46 of the member 42.

A leaf spring '70, which passes beneath pin 40 and is retained in position relatively thereto by seating within a notch 72 in such pin, is bent upwardly and into abutment with the bottom face of the body and then through an opening in such face, to pass within the groove of the body and position an end wall 76 at the rearmost portion of the body. A coiled spring 78 is retained within the groove of member 48 and presses against the end wall '76 and finger 58, tending to force the pusher against a clip 80 of associated staples 1 such as those described in my copending application aforesaid, or against clips of closures, points or brads, assembled in substantially the same manner.

At the forward end of body 42, there is mounted the vertically extending guide sleeve 82, of sheet metal or similar material, bent to substantially rectangular contour, the lower end of the sleeve being cut and bent away from the body thereof, to provide a pair of tongues 84, receivable around the body 42, to which it may be secured in any well-known manner, such as tack-welding.

Within the passage-provided by sleeve 82 is reciprocable a plunger 86, formed, in like manner, of sheet metal, bent into substantially rectangular shape and of such dimensions as to fit substantially snugly within the passage through sleeve 82. The sleeve and the plunger, while each is formed substantially rectangular, each has the Through slot 56 in the upper,

respective forward walls 88 and 90 thereof disposed in such relation that, when the sleeve and plunger are assembled on the body, the planes of these walls will be the same as, or parallel to, the planes of the end edge of body 42 and members 48.

One or more nubs 92, pressed or otherwise formed in the outer surface of plunger 86, are provided to retain upon the plunger the driver 94. The latter is secured to the forward face of wall 90 so as to be retained in fixed relation, and substantially parallel to the end edge of body 42, for purposes hereinafter appearing.

The upper end of the plunger is closed by a handle or knob 96, formed in any well-knownmanner, the handle providing an abutment for a spring 98, housed within the plunger and the sleeve, and bearing against a wall 100, formed by bending inwardly a portion of the metal at the lower end of sleeve 82.

In order to retain the plunger in assembled relation with sleeve 82, a resilient member 102 is anchored under a struck out portion 104 on the outside face of the guide sleeve, and is then bent to extend upwardly and then through an opening 106, in the sleeve and within a slot 108 out through the plunger metal. The spring is then bent outwardly to provide a retaining finger 110 in contact with the outer face of sleeve 82. The portion 112, which engages within slot 108, serves as a stop, limiting upward movement of the plunger. By manipulating finger 110, the interengagement of the portion and the slot may be destroyed so that the plunger may be removed from within the sleeve 82.

The driver 94 is substantially only of sufiicient thickness to engage against a single staple of the clip 80, which, by the action of spring 78 and the pusher 52, will have been positioned in abutment with the end wall 114, such end wall being secured to the sleeve in any well-known manner. The driver and the end wall are so dimensioned as to be in immediate sliding contact in order to permit ,efiicient engagement of the driver end with but a single staple when the latter is positioned in abutment with the end wall.

In this embodiment of the invention, the end wall is formed as a pivoted closure, mounted upon a pin 116, which is supported upon a bracket 118, secured to the outer face of the sleeve. A spring 120 normally tends to rotate the end wall into abutment with the end face of body 42, the forward wall 88 of the sleeve being cut away to permit this. A spring finger 122, in this case the end portion of the end wall, is thereby brought into frictional and interlocking engagement with a pin 124, mounted upon a bracket 126, similar to bracket 118, and at the opposite side of the sleeve. In this manner, the end wall is permitted to be swung away from the body 42, and clips of staples may be loaded into the device merely by sliding them over the flanges 50 of member 48, after the pusher has been retracted, and is so held.

In some cases where a staple has been separated from its clip by the action of the driver, but movement of the driver, to close the staple about the material with which it is desired to assemble it, has not been completed, it is necessary to have apparatus related to the driver so that the staple, which has thus been separated, will be returned to its position and held ready for the next succeeding operation. This apparatus also is operative, in case a single staple is fed down through the apparatus and requires The forward end of the leaf is cut off atsubstiuitially the same angle as the'end angles of body the portion.

To assemble the portion, it is slipped through the open end of the member 48, as made accessible by; swinging the end walli114 away from body 42,.

and is locked in place by bringingthe base' 13 8 of portion 128 against a pair of stop lugs 140,

edge of an opening 144 in end wall 114. fllorrnal portany free staple which maybe fedjinto ,the

spacing between body.,42 ;and'end-wa1l114; Q As the driver moves downward yjfl ain stapie, which,'as can be seen, will be carried by leaf 134, the leaf will be pivoted downwardly until the fastening operation has beencompleted',

at which point the staple will have completely cleared the end edge of the leaf.

In order to cooperate with the driver and to effect eflicient clinching of the staple,. there is provided within a recess 146, formed in the base 36 by spinning the metal, or by any other suitable method, a reciprocable wall 148. The wall is retained normally in raised position by a spring I 150, bearing thereagainst, and against a bottom 152, pressed or otherwise inserted into, the opena slot 154 is formed by punching or in'any other manner bending the metal of the wall downward- 1y, to provide a pair of oppositely disposed flanges 156 upon which are pivoted the anvilmembers 158. These members depend downwardly within the slot and bear against amovable'base 160,

housedwithinwall 148. Base 160' also provides a housing fer a spring 162, which bears against the base and against the bottom 152, to force the former into contact with members 158. The spring 162 is weaker than spring 150 so that when a staple is driven against members 158 by driver. 94, the movable base will first be depressed so that the members will-be extended downwardly and their curving surfaces 164 will provide a gradually sloping surface for initiating slow bending ofstaple will penetrate the same, substantially direst contact between the driver, the anvil members 158 and the wall 148 is effected, so that the latter is driven downwardly against the action of spring 150, until the wall seats against bottom 152, whereupon the surfaces 164, which are now slots are turned so as to retain the slot 154 substantially parallel to the plane of ,the'driver 94, and therefore of the staple driven thereby.
